By reference'to the dagra vsho 7 it will be seen that thev headsof cent loops ,lo

respective adjacent stitches in the fabric are staggered or out of horizontal alinement. Hence a machine constructed in `accordance with this invention may be employed advantageously for repairing or strengthening a piece of fabric, and furthermore, various designs on the surface'of the fabric can be produced by using differentv colored 'threads in the respective sets of needles.

1. In a sewing machine, the combination of two sets of alternately `operated needles, a plate formed with anopeni for the passage of the needles, means nfr passing a looped thread through all the `loops of each set of needles when the latter are driven down below4 the plate, and means lfor holding the looped thread whilethe loop forming means is withdrawn.

2. In a sewing machine, vthe combination of two/sets of needles to form alternate rows of loops, means for inserting a continuous looped thread through leach successive row of loops, and means for holding the looped thread while the respective rowsof loops are drawn into the material.

3. In a `sewing machine, the combination of two sets of alternately operated needles, a lpl'a'te having an openin for the passage of the needles, 4a "horizontay disposed needle located under the throat plate to form an elongated loo in the row of loops formed 'by each set o? needles, and means for holding lthe looped thread while the horizontal needle Iis be' withdrawn.

4. In a sewing machine, the combination of a needle for forming from a continuous thread a lplurality of elongated loops, the connecting portion of 4each loop extending from one Ilegof one loop to the leg of the adjacent loop, .erated needles, one set of needles for loopsv around the .legs of one set of elongated loops, and the other set of `needles forming loops around Vthe legs ofthe other set of elongated loops.
